  • tempfail for bar LF

    From Marco Moock@21:1/5 to All on Sun Sep 22 11:02:22 2024
    Hello!

    I am running 8.17.1.9-2+deb12u2 from Debian.
    This has been patched to handle bare LF/CR chars.

    I now have a broken Cyrus calendar server that sends bare LF:

    sendmail[65816]: 48M8gGlI065816: collect: relay=localhost, from=<mm@dorfdsl.de>, info=Bare linefeed (LF) not allowed, where=body, status=tempfail
    cyrus/https[65811]: smtpclient: unexpected response to EOT: code=421 text=4.5.0 Bare linefeed (LF) not allowed

    Is there a special reason for the tempfail in that situation or should
    that be a permanent error? Mail will be sent to the MSP, if that
    matters.

    kind regards
    Marco

    421 is used to drop the connection to avoid misinterpreting
    further input (things might be "out of sync" now).
